1 0 all whom it may concern:

Be it known that we, F nrrz F INOKH, residing at Essen, Germany, and PAUL Kniicnn, residing at Essen, Germany, both subjects of the Republic of Germany, have invented a certain new and useful Improvement in The object of this invention is a dumping receptacle of the kindmentioned, in which a separate mechanism is provided for each side wall, by which mechanism the latter, when the discharge takes place on its side, in the tilting movement of the bottom towards said side, is so controlled that an enlargement of the discharge opening is effected and that, in tilting towards the opposite side in which case the force-closed hinged connection between the side wall and the bottom is maintained, no action is exerted on this side wall by said mechanism.

In the drawing, in which an embodiment of the invention as applied to a railway dumping car is shown,

Fig. l is a cross section through the car in the loading position, i

Fig. 2 a similar section of the car in dumping position towards one side, and

F ig. 3 a similar section of the car in dumping position on the other side. I

On the underframe A of the car are rigidly secured parallel to each other the twoend walls A Also to the underframe A, at the front and rear end of the car, are placed two bearings a symmetrical to the central longitudinal plane of the car. Said bearings are to receive two through shafts B, on which are mounted, in opposite pairs, crank arms 6 The crank arms 6 are each connected to the bottom C of the car by a rod D. Further to the underirame .aresecured abutments a permitting an inwardly directed rotation only, of the crank arms 6 when the latter engage them. Again on the bottom C of the car, abutments the bottom C, and on each 0 for the rods D are provided, which permit likewise said links to turn only inwardly.

Each of the two side walls E of the car is provided at its lower edge with a laterally open bearing 6 which engages, in the loading position of the car (Fig. l), with pins 0 of the bottom C so, that there is formed in a well known way a force-closed hinged connection, which automatically is released on the discharge side, in the tilting movement of the bottom, while this connection is maintained on the opposite side. At their upper edge the side walls rest, in the loading position ofthe car, in open bearings a provided on the end walls A The side walls F) are guided by links F, which are pivoted on the end walls A On the front as well as on the rear end of side of the cen plane of the car, is crank composed of two connected together.

tral lon itudinal mounted an angle arms (1 and G rigidly The arm G of each angle crank is connected with the side wall E, lying on the opposite side of the central longitudinal plane, by a connecting rod H, which passes through a slot (not shown) in the bottom C, the pivot connecting said rod H to the side wall being coaxial with the respective bearing 6 The second arm G of the angle crank G- G is connected with a crank arm Z0 by a rod J, said arm being secured on a shaft K, journalled in the underframe A on the same side of the central longitudinal plane. These parts are so arranged that the axis of the pivot connecting the crank arm G with the rod J, coincide, in the loading position of the car (Fig. 1), with the common axis of the pivots which connect the crank arms 5 journalled on the opposite side of the central longitudinal plane, with the corresponding rods D.

Furthermore, in the loading position of the car (Fig. 1), the crank arms 70 are turned in the opposite direction to the arrow m beyond their inner dead center position, and the crank arms G are turned in the direction of the arrow y beyond its outer dead center position, through a certain small angle. Both the shafts K, rotatable by hand wheels 70 and locked against rotation in the direction of the arrow 00 when the car is in the loading position, also carry at each end a crank arm 70 which is connected by a rod against M with a crank arm- 6 mounted on the shaft B and extending in the opposite direction to the crank arm 5 lVhen the car is loaded (Fig. 1), the load exerts a pressure on the side walls E in the discharge direction. Since the bearings c of the force-closed links connecting the side walls with the bottom are open laterally, the pivot pins 0 cannot take up these pressures. They are, however, taken up by the rods H andfurther by the crank arms G. Since the latter are near their dead center position, they afford an automatic lock so that the car is secured in a high degree against an unintentional discharge. In the event that this automatic locking action should become released by blows in the travel of the car, and, at the same time, the locking of the shafts K rotation in the direction of the arrow :0 should be ineffective, a further guarantee against unauthorized discharge is provided for in that the crank arms arev in the vicinity of their inner dead centers. Accordingly, when the crank arms G turn in the direction of the arrow 1 under the influence of the forces transmitted by the connecting rods H in the direction of the arrow y, the crank arms 70 can only turn through a small angle in the direction of the arrow m, till they reach their dead center position.

This is obviously practically immaterial.

When the car is to be dumped on the right hand side, for example (Fig. 2), the crank arms 70 located to the left of the central longitudinal plane, after the lock of the shaft K is released, are turned inwardly a small. amount in the direction of the arrow {12 by means of the hand-wheels 70 This rotation is transmitted by the links M and the crank arms b to the crank arms b so that the latter are also turned inwardly. Under the weight of the load the bottom C then tilts automatically towards the right, turning on the pivots which connect the left hand, at this time remaining stationary, crank arms 5 with the corresponding rods D, resting against the abutments and therefore moving together with the bottom. Simultaneously with the left hand crank arms 70 the crank arms 70 rigidly connected to them, are turned. This movement is transmitted by the rods J to the angle cranks G G and, from there, to the right hand side wall E, which turns outwardly in r the bearings car. This movement of the side wall can take place unhindered, since the bearing 6 of the force-closed pivotal connection e 0 connecting the bottom and side wall, is laterally open and therefore said force-closed connection is released automatically. The side wall E then swings in the direction to enlarge the discharge opening.

During the tilting movement of the bottom, the forceclosed connection between it and the left side wall E is maintained, so

ing position,

that the side wall is raised in the usual way and moved inwardly The rod H, which engages this. side wall, maintains at this time its position unchanged relatively to the bottom, since the axis of the pivot, which connects the right hand rod J with. the corresponding crank arm G coincides with the pivotal axis of the bottom and, therefore, the crank arm G cannot make a movement relative to the bottom. The pivotal connection between the left side tom, therefore, remains secured even during the dumping, by the left hand rod H'.

In the return of the bottom into the loadthe crank arms 10 70 (lying to theleft of the central longitudinal plane) are turned back, in the direction opposite to the arrow a7, into their original position. This movement of the crank arms results in the bottom of the car being also turned back into its original position, the side walls E also returning to their original position simultaneously.

The dumping of the car towards the left side (Fig. 3) requires no speci 1 description, since the various operations correspond exactly to those occurring when the car is dumped towards the right. It may merely be stated that, in contradistinction to the first case, the left hand crank arms 71: 10 remain stationary and the movement of the bottom and of the right hand side wall is accomplished by the crank arms 76 k lying to the right of the central longitudinal plane of the car.
